RMT suspended strikes planned on the Piccadilly and Hammersmith and City Lines, after management made significant concessions in Acas talks.

The union says it has achieved "all objectives" in the Picc Line dispute. According to an RMT circular, management have confirmed that there are "no plans to extend the use of Cockfosters Depot facilities, and that all drivers will continue to receive full familiarisations. A SPAD policy briefing with management will take place in conjunction with Trains Functional Council reps to seek to resolve any negative perceptions, and to ensure the process is undertaken fairly and consistently. Assurances have been received on other issues, and Brother Gary Fitzpatrick's [a victimised union rep] safety has been protected by removing the other party from the workplace while the matter is resolved through the proper procedures."

Undoubtedly the added pressure of the fleet issues on the Picc made management keen to avoid a strike, but what has won this dispute is the organisation and resolve of RMT drivers in Picc Line depots. It's proof that it's not clever negotiations, but workplace organisation, that gets the goods.

RMT says it is satisfied with assurances received from management on the Hammersmith and City Line about adherence to procedures, and has suspended the strike there too. Driver members will need to remain vigilant to make sure the bosses keep their promises.
